Mack EY. Made in 1943.707 ci displacement. As you can see both manifolds are on the right side.

Ah, sorry, most of the time I’m used to seeing 707 motors broken down into just A, B, and C. Never seen an updraft carb on a 707 either... must’ve been a military only thing...

Regardless the engine in that LT is a 707B...

Thanks guys. This truck pre-dated the B Model. I forgot what model it was. It was 1920's or 30's. But the guy was saying Mack used International motors in them because at the time they did not make their own engines.

 

So I didn't know if that was true or not.

Well Mack made their own engines since atleast the AC which were built during WW1 so we know that much isn’t true, so what’s to say the rest is?

ya,,,,but you got to admit,,,,,those older engines,,,,although alot less horsepower than these modern engines,,,,why is it they sounded alot better,,,,lol...bob

That’s because back in the day nobody engineered the sound, they just let nature determine the sound... now a days they engineer the sound so much there are teams of people who can play songs using a car engine...

That and while some of us don’t mind being deaf taking care of and driving with these old engines... not everyone does... and unfortunately those are the people making the important decisions...

My bet that's EY 707ci Mack engine taking to account the production year.

C motors have the exhaust manifold on the driver side of the truck, this one has it on the passenger. The thing that leads me to believe it’s a B motor is the pattern on the block. My ‘53 has a B motor in it so the year isn’t really a reliable way of figuring out which motor I’ve learned...

Here is a 1947 LT that I just picked up. The owner called me and told me he was not able to finish the restoration . He was 11yrs old when he and his Dad picked it up at the San Francisco Mack dealer!! It has the Mack 707 thermodyne gasser. the 47 thru 49 were on a different frame than the 50 on LT's

Does it still have the spread frame rails? Also looks like that’s a 707B motor to me. It could also be an A but it seems more like a B motor to me.
Please give us any information you have about the truck!

Also do you plan on restoring it? It’d be the only 707 powered LT on the road!

A part of me hated to do this, but there's no other way unfortunately. Does anyone know what happened to any of these trucks? I was trying to find Jake's LTL and unfortunately I discovered that he most likely sadly passed away a few years ago. My dad fell in love with the LTL after trying to find ideas of what he wanted his truck to be in the future, especially since it seemed to match the looks of his dad's old L model firetruck that the two of us have been working on for the past few years. I was hoping that I'd be able to find it on my own but it turns out that plan was more wishful thinking... Any help is much appreciated!

I forgot to post earlier about this beautiful B. It is a really great restoration. My one question is why is the tach not in the dash panel and clamped alongside the steering column? I'm just curious.

Back in the day you didn't tend to care so much about RPMs just how fast you were going, thus many of these trucks were built without them. So in the more modern age an easy solution was just to stick it on to the steering column or dash board, rather and cut a big hole in the dash for it to sit in.

My friend's trucking company made one using only old trucks but they started doing pickup trucks and didn't have a single Mack! I like the idea of doing a BMT calendar with the highest voted pictures from each month of the year previous to that of the calendar.

Does anyone know where any of these trucks are to this day. Im gavin chase the grandson of gordon and i would like to know where one is before he passes

 

I wish you the best of luck finding your grandad’s old trucks. If anyone knows where they are you’re in the right place, clearly you’re grandma’s old H model is still out there somewhere, probably in Massachusetts. That’s just what I’ve been able to gather so far... Make a new topic on the Trucks Wanted section of the site with any other information you have to try to bring a little more attention to your search.

Sad part is that there is a market for trucks like that and no manufacturer is filling it.

That’s why so many of these old dogs are still working...

Volvo medium duty?

Very big...

I expect this to be something along the lines of bringing back an old nameplate or an electric tractor... can't think of much else that would be considered "big" by anyone that we wouldn't know about already.

sure would like to come out of retirement  and work in that shop. .looks like the days  when a mechanic rolled his toolbox to a job;   NOT a computer.. my day off would be spent with a loader hooking and moving all the iron outside so oil would coat the top half of gears in drivetrains . good to have all the iron  , but  dampness from ground raises havoc  as the yrs go by . 

They've got all their most useful parts under cover on palats...

Other than that, yeah I love the place, they only work on old iron so the shop is set up for that kind of work.

Damn if that daycab MH wouldn't make a fine lowboy tractor.

I went back and looked, I think all the MHs are integral sleepers in this guys yard. If you want the V-Mack one sitting there it looks like it wouldn't be too much work to fix up again. I will say, these trucks are constantly being parted out so if you want to get a truck out of there you've gotta do ti when you can. The MHs and the line of CFs are still sitting where they were in the original pictures for the most part, but some of the other stuff moves around a bit.

I guess I forgot to let you all know where I found this stuff, well I won’t tell you directly yet but all you need to know are in the background of these pictures... they’ve been helping me out with my old LS and I figure they deserve the attention...

If you end up there be sure to tell them what you’re working on and they’ll be able to point you in the right direction...

Anybody know what engines and transmissions were in the Mack MH Ultraliners that were owned and operated by Mack for use at their factories? I’ve included some pictures to hopefully help clarify what I’m talking about...

Not likely, although I could bring some of it on the back of the B42.

It’s be fun if you positioned just the cab and hood on the trailer as if the thing had its chassis stolen out from under it so fast it left the body in place...

These updates are getting me excited for your rig... maybe even as excited as you! Seeing classic trucks like this get back on the road in such a right way just fills a hole in my soul left by living near a junkyard that stops people trying to preserve history... yet they keep the things that THEY find nice to look at...

Thanks Paul. I have old Motors Manual that covers up to '59. Also found old timer in PA that has rebuilt 354 sitting in floor but not ready to part with. But he is willing to help with any info.

I told owner to put ATF/acetone in cylinders to soak for a while and squirt rockers for a week before trying to roll over. Its going to be interesting!! 

Things like this make me wish I joined BMT a few months before I did... we messed up our 707 because we didn't think to clean up the engine and gas tank before trying to start it up for the first time... I guess it all worked out though, as the crack in the engine block was there before we got it, we just didn't realize how bad it was, and now that problem has been fixed... and bonus that the new block is easier to maintain, not to mention the Mack logo inscribed on the side of it.

Still, y'all would've helped us save a bit of time and money on the heads...

Some kid figured out a genius way to load & unload doubles more efficiently...

European edition of this strategy evidently...

There were a lot of LT's up here on Vancouver Island of S&S trucking with HALL-SCOTT engines chassis numbers 1011 - 1017 and quite a few on the lower mainland with 707 engines chassis numbers lt-2d1224 & lt-2d1225. These were log trucks with off high way suspentions 11 & 12 foot bunks and about 25 ton trailers.Pictures show them to be way over loaded for size of truck. 

Sounds like the right application for the way over built 707 motor...

L-model firetruck fenders are different in relation to a common L. Worth to note they firetruck ones were of two different styles either (and I don't mean Left and Right) but neither of them woulf fit correct on LF or LJ.

I never noticed the difference until you just brought it up, I see now how the firetruck fenders have a little extra bit hanging in towards the tire. I guess that would cause some rubbing while turning with the right sized tires for an LF.

But LT fenders also won't work because the frame rails are further apart so they wouldn't sit right on a more 'normal' LF frame, even if you managed to line up the holes... figured I'd mention it...

Also I'll let you know I had to get some parts out of Oregon to get my LS running again, and I'm all the way out on the East Coast... So if I were you, Conelrad, I'd find one that works and then get it shipped to you, otherwise you'll spend forever trying to find one close to you. I got really lucky by finding a shop close by with a few of the parts I needed from and engine they worked on decades ago, but I used all of them...

Thanks! I'll try it the next time the website knocks something on it's side...

Looks like a sweet project! Can't wait to see it at shows in the upcoming future...

Whoops!.. Many thanks for the reference picture. For some reason I thought LT rails were of the same shape as a common L-model had with just cab mounts etc moved backwards. Now I clearly see I was wrong. Probably I never crawled under an LT chassis since it's off a focus of my interest. One of the greatest looking trucks no doubt but my personal preference is an all Mack drivetrain. LT's with 707 were described as produced in some quantities but I don't remember ever hearing of any survivors.

I bet they weren't very popular, that engine would've been swimming under that hood with the space. Any 707 can fit under the hood of my standard L, and the LTs were designed to accommodate bigger engines, hence the spread frame rails at the front. Using the LT's frame rails on the W allowed for a really low doghouse because the engines could sit deeper down in the frame rails, pretty interesting that it wasn't a more popular design... in my opinion atleast!
